I found a strange thing about the dead corners with the pen. If I use my tablet without keyboard I have dead corners when writing. in hardware I found a hid mouse with wacom drivers from 2006. if I connect the keyboard I found a second hid mouse with Microsoft drivers form 2006. in that case the dead corners are gone. I think the dead corners are a problem with the hid mouse drivers. but I can not update them. does anybody has a solution for this.
